Aaron Judge, Carlos Correa and Nolan Arenado lead a new generation of All-Stars, among 12 first-time starters elected by fans for Tuesday's game at Marlins Park.
The dozen first-time starters are the most since voting was returned to fans in 1970. There could be a 13th first-time starter depending on who the National League selects as its designated hitter.
Two of the first-time starters are from the Houston Astros, who have the best record in the major leagues: Correa, the shortstop drafted first overall in 2012, and outfielder George Springer.
Cleveland's Jose Ramirez overtook Minnesota's Miguel Sano in the final days of balloting to win the AL third base spot by about 54,000 votes, Toronto's Justin Smoak bounced back to beat Kansas City's Eric Hosmer by 555,000 at first base, and Tampa Bay's Corey Dickerson rallied to win at designated hitter by nearly 75,000 over Seattle's Nelson Cruz. The Royals' Salvador Perez won at catcher.
